+Qt has two great timers, one that repeats an action after a certain interval, and one that is meant for one-off operations. They call these `QTimer` and `QTimer::singleShot` respectively. This post is going to assume that we're working with a class named `Test` that inherits `QObject`.
+
+Let us first look at the one that repeats. This code needs to be inside a class that inherits `QObject`.
+```c++
+void Test::callbackRepeat(void) {
+    // Code that executes when the timer times out
+}
+
+// ......
+int interval = 1000; // Units: milliseconds
+QTimer* timer = new QTimer(this);
+timer->start(interval);
+connect(timer, &QTimer::timeout, this, &Test::callbackRepeat);
+```
+
+Now for the one-off...
+
+```c++
+void Test::callback(void) {
+	// Code that executes when the timer times out
+}
+
+// ......
+int timeout = 1000; // Units: milliseconds
+QTimer::singleShot(timeout, this, &Test::callback)
+```
